Specification of Letters Patent.

Patented June 11, 1907.

T all whom it may concern:

Be it known that I, WILLIAM M. STEVEN- SON, a citizen of the United States, residing in Indian Orchard, Massachusetts, have invented certain Improvements in Woven Fabrics, of which the following is a Specification. My invention consists of a woven fabric having a pattern in relief formed upon one face of the same in a manner which enhances 1o the attractiveness of said pattern as compared With relief patterns heretofore produced.

In the accompanying drawing: Figure 1, is a face View of a piece of woven fabric hav- I 5 ing a relief pattern formed thereon in accordance with my invention, and Fig. 2, is a section of part of said fabric on the line aga', Fig. l.l

1, l, represent the warp threads and 2, 2, 2o the weft threads of a piece of fabric which may be woven in any desired manner, that is to say, either with a plain weave, a twill, a patterned surface or an unpatterned surface, my present invention having no reference to the character of what may be termed the main or ground fabric, but relating especially to the formation of patterns in relief upon the face of said ground fabric. Each figure of the relief pattern is composed of a Weit thread of a length sufficient to form the figure, this relief weft thread being interwoven with the warp threads of the main fabric in a novel and peculiar manner, the interweaving beginning at the center of the thread and terminating at the ends of the same, after the figure has been produced.

In the fabric shown in the drawing the pattern comprises two figures, one inside of the other, each figure being composed of a weft thread 3, the starting point of each weft thread being at the point 4, and the finish at the points 5. In producing either of the 'figures shown a limited number of warp threads 1 are raised, and the relief weft thread 3 is drawn under the same and over the tops of the remaining warp threads on each side of the raised group until it projects to an equal extent on each side of said raised group. On the next operation a group of warp threads on each side of those first raised is lifted, the warp threads first raised remaining down, and one end of the relief weft thread is passed under the right hand group of said raised warp threads and the other end under the left hand group of said threads, and each end is drawn tight before changing the shed of warp threads, these operations being repeated with different groups of warp threads in accordance with the desired pattern, until the ends of the relief weft threads are reached.

The weaving of the ground fabric proceeds coincidently with the introduction of the relief weft threads. I/Vhore each of the ground weft threads consists of a plurality of independently introduced strands, the latter should be introduced and beaten up before the introduction of the corresponding portion of the overlying relief weft thread, but where the ground weft threads are single and as large as the relief weft thread they may be beaten up either before or after the introduction of the overlying portion of the relief weft thread.

I prefer to use for the relief weft thread a tape or ribbon, and to impart a partial turn or twist thereto as it passes from one shot or insertion to the next, as indicated at G, in Fig. l, these turns or twists increasing the height of the relief and adding to the attractiveness of the `ligure at the points where they occur.

I am aware that it has heretofore been proposed to produce a fabric havinga pattern on the face formed by relief weft threads independent of those of the ground fabric, but in such prior fabric, each shot of the relief weft thread. was disconnected from the next, whereas in my fabric a single continuous thread forms successive shots or picks, or is .introduced into successive sheddings of the warp threads. I am also familiar with the fabrics produced in what are termed swivel looms, but these are distinct from my invention in that, although the relief weft thread may be continuous, it docs not appear continuously upon the surface of the fabric, but is buried in parts or passes from one face of the fabric to the other.

I claim:

. 1. A woven fabric having a figure woven in relief thereon, and composed of a weft thread extending continuously throughout successive shots and lying wholly upon the face of the fabric.

2. A woven fabric having upon iis face, a relief figure consisting of a continuous weft IOO nl o

thread shot successively under different sheds of tying warp threads, but lying throughout on the face of the fabric.

3. A woven fabric having upon the face of the same a relief figure composed of a tape or ribbon, interwoven as a weft thread with a plurality of sheds of the warp threads of the fabric.

4. A woven fabric having upon the face of the same a relief iigure composed of a weft thread passing successively under different sheds of tying warp threads, and having a partial twist imparted to it in passing from one shot to the next.

thread which is first interwoven with the warp threads of the fabric at a point between its opposite ends, subsequent interweavings extending progressively toward the ends of the thread.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

WILLIAM M. STEVENSON.
